In 2007, Brower and I, together with J. Polchinski and M. Strassler[1]},
provided a coherent first principles treatment of the Pomeron. In the large-N QCD-like theories, we used curved-space string-theory to describe simultaneously both the BFKL regime and the classical Regge regime. On the basis of gauge/string duality, this allows us to deal with high-energy small-angle scattering in QCD. The problem reduces to finding the spectrum of a single j-plane Schrödinger operator. Our results agree with expectations for the BFKL Pomeron at negative t, and with the expected glueball spectrum at positive t, but provide a framework in which they are unified.
